TECHNOLOGY OF MANUFACTURING UNIVERSAL CLUTCH FOR
WELD-FREE, TAP-FREE, TAP-FREE CONNECTION OF PIPE CUTS
IN HIGH PRESSURE PIPELINES
Kashcheev Vladimir Sergeevich
The manufacturing technology of a universal coupling for weldless, threadless, flangeless connection of pipe segments in pipelines with a nominal working pressure of 150 or more atmospheres. The implementation period is 1.5-3 months.
I have developed a technology for manufacturing universal couplings made of various materials for WELDLESS connection of pipe segments (metal and plastic) of various diameters and purposes. This connection method differs from the well-known Georg Fischer technology in that the pipe segments are not fixed by compressing the sealing material around the pipe, which does not ensure the joint strength at high pressure and when the pipes are placed in a vertical plane, but by mechanical fixing of the pipe segments in the coupling.
The strength of my connection is comparable to the strength of a one-piece pipe with a nominal working pressure of up to 150 atm . In addition, the method of the proposed connection, carried out manually, eliminates significant physical effort during installation. The use of a new coupling eliminates threading and welding of flanges. Connection and is carried out at various angles.
The value of the coupling lies in its widespread use, but above all, in its use in harsh industrial conditions: in mines with a gas polluted atmosphere and increased explosion hazard, in factories, etc.
